To all 'whom t may concern: l

Be it known that' l, ROBERT C. CAUGHEY, a citizen of the United States, residingv at Dixon, Lee vCounty, State of lllinois, have invented certain new and useful improvements inPlowframes, of which the following is a specification.` f

This invention relates to a plow in which there is a frame with means to provide for the substitution of diderent plow bodies therein, or the adjustment of plow bodies at different distances apart.

Among the objects of the invention are; to provide a frame in which separate plow bodies are interchangeably attachable; to provide means for variably spacing the bodies apart; to utilize the same frame for various plow widths; to accommodate different plow bodies on the same frame; to eliminate the trouble and delay caused when one of the plow standards is sprung or damaged while plowing; to provide a sectional frame to or from which sections can be added or subtracted; to insure that one of the plow standards will be sprung or broken instead of the main plow or frame; and in general, to provide the improved construction, combination and arrangement of parts as herein set forth.

.ln the accompanying drawing, Fig. l is a side elevation of a plow constructed in accordance with the principles of this invention;

Fig. 6 is a sectional detail taken on the line 6 6 of Fig. llc.

Referring more particularly to the draw ings, the numeral l designates, generally, a plow-frame section with staggered sections 2 and 3 formed integrally and preferably as apart of the same steel casting. Attached to the front ends of 4these staggered sections by any suitablefastening devices are stub plow beams 4 and 5, which are joined at their outer ends by a connector 6. Attached to each of the beams is a draft or clevis plate i', commonly provided with a plurality of Serial No. 284,35 7.

therectangular openings 8 thereof, any one of a number of beam ends 10, ofstandards ll, for supporting plow bodies l2, the beam ends 10 extending across approximately one- .half of the transverse space of the box opening 8, and each beam ispreferably formed with a perforation 3l and with a longitudinally extending shoulder portion 33 on each side ofthe opening, for receiving a correspondingly faced edge of a wedge block 13, which is also provided with a projection la' adapted to extend into the perforation 3l. t the opposite side of this wedge block 13 it is formed with a wedge slot l5 in which a wedge bolt 16 is adapted to be seated, the wedge bolt being inserted up through the perforation 9', and formed 'with a threaded extremity 17' which extends loosely through one of the openings 9 in the frame plate 1, where a washer 18 surrounds it with a nut mounted on the threaded portion, for'drawing the wedge bolt upwardly and securely clamping the wedge block 18 and the beam standard lOin place. With this construction -it is obvious that the beam 10 could be dis- -upon the-sizes of the various parts, and for convenience it may be taken as a difference of two inches, so that the movement of the f plow beam or standard to one side or the other of the recess 8 will vary the transverse fposition two inches. lt is obvious that this adjustment may be utilized for employing plow bodies of various widths in the same frame, for example in the construction shown, assumingthat the inner-most plow beam centers of the .frame l are ten; inches lim at oney side of the frame casting 1.

be at the lesser distance.

apart, the adjustment of one of the plow ing 1 is. a supplementary casting 2O which is preferably formed with lateral connection ears 21, by means of which it is attached to corresponding connection ears 22 formed Y Y At the other side of this supplementalframe 2O Aare other attachment ears 23 .by means of which any number ofsections 2O may be attached in succession. Extending from the outer side of this attachable extension 20 is a brace 24 which is attached by means offasteningv bolts 25 to one of the' stub beams 5. This supplemental frame 20 is formed with asingle recess S for receiving and attaching the plow standard beams, and .in the form shown, with only two adjust- Vments in the frame section 20 it is possible to vary the three plow standards on either a 12er 14 inch width, as shown more clearly by Fig..5, for byV leaving the middle standard in the. central position, as shown, and having the two outer standards in' their outermost positions, the standards will be at their greatest possible distance apart, and if theyare both moved inwardly they will With this -con- Ystruction itl is obvious that either 12 inch or 14 inch plowscan be used in connection with the standards. p

It will be apparent that the plow bodies which can be used with a plow frame of this kind may be varied in character; for example either 'stubble or brakerlbottoms may be used, or bodies of different widths may be used, or the same plow as a whole maybe easilyV changed to a two or three bottom` implement by simply adding or removing the plow bodies by means of the wedging bolts .and blocks. Tith this construction' any one of the plow bodies can be separately removedand another one substituted, so that if one" standard becomes sprung or damaged in any. way it` can be removed and a new one substituted. By having la plurality of sections the plow can be varied to cutas many furrows as desired, and by varying the width of the sections the distance between the furrows can also be varied at will. This sectional frame structureV Vreadily lends itself to various changes and combinations because of' itsadjustability. It is also easily'manufactured and shipped because of the few partsV and thev facility with which theyV are 'assembled and the small space which .they occupy ywhen theparts are taken apart; it'rreduces the cost toV themanufacturer, the'- dealer, and

the user because each implement is capable `will travel in the inside furrow. Thiscastor wheel may be attached in any convenient manner, but for the purpose of illustration I have shown a portion of' structure such as shown in my applicationrfiledJanuary 13, 1919,V Serial No. 270,774, to which referencemay be hadv for a complete understanding of this attachment.'

As shown, this castor wheel' connection comprises a bracket 26, secured to the rear of the plow standard 11, and a benty axle 27 has the upright portion 28 thereof connected to the bracket to support the axle. The castor'wheel (not shown)l is journaled to they rear end ofthe axle 27 in any suitable manner so as to travel behind the plow in the furrow.

When a threebody plow isto bechanged to a' two-body plow, it is necessary only to remove the .middlestandard and then take the rear. standard out with the plow bottom attached and Vinsert it inthe middle opening. The frame section` 2O does not have to be removed as it is not in the of the successful working of the plow. v By this vit will be seen a three-plow can be changed of which is to be determined by reference tothe appended` claims.

I claim: 1. A plow comprising. a frame with a socket, a plow body having a supportingr `beam which extends" Vforwardly into the socket and is adapted to be optionally positioned at opposite sides of the socket, and

3. The combination vwith a draft frame havingfa vplow beam receiving recess 1open at incense the rear, a plow-body, with an individual beam extending forwardly into the recess, Va wedging block to engage the inserted beam, and a wedging belt having a fastening nut and adapted to tighten the block against the beam in the recess and hold them both in place therein.
